Description

C2 L-Erythro Ceramide (D18:1/2:0) is a high-purity, synthetic sphingolipid characterized by its specific stereochemistry (L-erythro) and defined acyl chain composition. This compound serves as a critical reference standard and a key building block in lipidomics research and the development of advanced cosmetic and pharmaceutical formulations. It is essential for scientists and product developers in the cosmetics, dermatology, and life science research sectors who require structurally defined, high-quality lipids to ensure experimental reproducibility and product efficacy.

Application

• Biomedical Research & Lipidomics: Used as a certified reference material for the identification, quantification, and metabolic pathway analysis of ceramides in biological samples via LC-MS/MS.
• Cosmetic Science: Incorporated into advanced skincare formulations to study and mimic the natural lipid barrier of the skin, aiding in the development of moisturizers and repair creams.
• Pharmaceutical Development: Serves as a precursor or intermediate in the synthesis of more complex sphingolipids for drug discovery and targeted therapy research.
• Cell Biology Studies: Applied in research to investigate the role of specific ceramide species in cellular signaling, apoptosis, and membrane structure.
• Analytical Method Validation: Critical for calibrating analytical instruments and validating testing methods in quality control laboratories.

Quality Control

Our C2 L-Erythro Ceramide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, MS for structural confirmation, and specific optical rotation measurement to verify stereochemical integrity. We provide a comprehensive Certificate of Analysis (COA) with each shipment, detailing all test results to ensure compliance with your research and development specifications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere for long-term stability. For short-term use, the product may be stored at 2-8°C. Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent moisture condensation.
